    I have a half dozen dial indicators and several mounting devices, as well as
    other precision measuring tools including a 12" dial caliper (0.001").  The
    dial indicators range from cheap Chinese 0.001" models, to good quality
    0.001", to a good old USA Federal 0.0001" unit.
    
    Recalling Joel's advice I am not quite sure of the set up he suggests, or
    how to pinpoint the exact location of arm's rotation point.
    
    Happy to help you if I understand the setup.
